The RSPCA today launched an investigation into the "horrific" killing of a fox shown on a BBC television documentary this week.

BBC Wales's Week In Week Out programme exploring the alternatives to hunting with dogs and the impact of a ban on fox hunting with dogs, which was broadcast on Tuesday, showed a man shooting a fox in cub and then kicking her.

Since then the RSPCA say they have been inundated with calls from members of the public who saw the programme and were horrified by the brutal and cruel treatment of the fox.

The man shown kicking the fox in the programme was not named but he was not disguised.

RSPCA Inspector John Paul said: "We have written to the producers of the programme to request an unedited version of the full programme in order for us to establish the version of events relating to this incident.

"It is our intention to begin inquiries and to carry out an investigation into the incident and to establish if any offence has been committed."

To prosecute, the RSPCA has to prove that unnecessary suffering was caused. The RSPCA believes that where there is a demonstrable need to control fox numbers, shooting is one of the most humane methods, provided it is done properly.

A BBC Wales spokesman said: "The RSPCA have been in touch with us about our programme on fox hunting.
